American Repairs Computer Malfunction That Grounded U.S. Flights

American Airlines has repaired computer malfunctions that grounded all its U.S. planes and is working to restart flights.

Normal departures may resume “soon,” Andrea Huguely, a spokeswoman, said in an e-mailed statement.

American’s grounding followed intermittent computer outages and was unrelated to heightened security concerns after bombings at the Boston Marathon that killed three and injured more than 170.

More than 420 of 1,183 American departures monitored have been canceled so far, according to industry data tracker

“It’s better to shut it down elegantly rather than have it fail spectacularly” and let delays pile up anyway, said Robert Mann, a former American Airlines executive who runs aviation consulting firm R.W. Mann & Co. in Port Washington, New York. “It’s a major inconvenience for customers and shippers across the system.”

The malfunction didn’t involve airline booking and reservation systems provided by Southlake, Texas-based Sabre Holdings Corp., said Nancy St. Pierre, a Sabre spokeswoman. American apologized to Sabre in a Twitter posting after blaming the flight-booking service for the malfunction earlier.

The third-biggest U.S. airline, AMR Corp. (AAMRQ)’s American is operating in bankruptcy and preparing to merge with US Airways Group Inc.
